Question

when cu reacts with nitric acid, will it produce h2 gas or not? justify your answer​

Answer 1

Answer:

Hey there ☺️ hope it helps

Explanation:

no it will no produce H2 gas and no reaction will take place as you can in the reactivity series , hydrogen is more reactive than copper hence copper can't displace hydrogen from its own solution.

Answer 2

No Hydrogen gas will not be evolved.

1) As the nitric acid is a strong oxidizing agent, so when cu reacts with nitric acid it will oxidize the H₂ to make H₂O.

2) The oxidizing nature of the nitric acid, when it reacts with any metal it produces a salt with water and nitrogen dioxide gas.

The chemical reaction of the situation:

Cu + 4HNO₃ ---> Cu(NO₃)₂ + 2NO₂+ 2H₂O
